Areas within the River Eden catchment are affected by Nutrient Neutrality
due to excess phosphorus levels in the River Eden designated site. This region includes the following Local Planning Authorities (LPAs):
The affected areas in the Eden catchment cover towns of Carlisle, Penrith and Brampton.
A detailed map of the area is shown below, and we also have mapped all the areas in England and Wales impacted by Nutrient Neutrality.

We would characterise the mitigation market in the catchment as very weak due to limited supply of phosphorus credits. Mitigation is being priced on a per house basis, with the cost of nutrient credits generally being quite high. Typically these are in the region of £5,000 to £7,000 per house.
The area has a variety of levels of nutrient stripping technology at the wastewater treatment works for phosphorus. New houses currently require between 0.1 kg to 0.89 kg of phosphorus mitigation per house. This creates significant opportunities for landowners looking at mitigation schemes.
We forecast demand outstripping supply for at least the next 2 years, despite new schemes coming online (see below).
There are approximately 82 wastewater treatment works in the River Eden Nutrient Neutrality area. 5 of the works have phosphorus removal technology and none of the works are scheduled for an upgrade over the current upgrade cycle (AMP7), running to 2025.
In order to meet the upgrade requirements that may be brought in under the Levelling Up and Regeneration Bill, referred to as the ‘TAL upgrades’, 5 treatment works will be upgraded to have phosphorus removal technologies by 2030. This means 77 treatment works will remain above the most stringent phosphorus removal requirements. Developments connecting to these treatment works will need more mitigation than those connecting to the 5 treatment works getting TAL upgrades.
As per our research into water treatment upgrades, we do not believe that it is likely that the water companies will be able to deliver all the upgrades in this cycle.
Natural England Strategic Nutrient Mitigation Scheme
The national-scale Natural England Nutrient Mitigation Scheme is likely to look at deploying mitigation solutions within affected areas of the River Eden catchment. These schemes may start to come online at the end of 2023, however exact timelines are unclear. The scheme is focussing on nature-based solutions such as wetlands and catchment management methods.
